The OSCAT BASIC library provides many low-level — but nevertheless very useful — functionalities. The following are especially worth mentioning:

  • Mathematics, complex mathematics, vector mathematics

  • Arithmetic functions

  • Geometric functions

  • Pulse generators / signal generators

  • Signal processing

  • Physical transformation calculations (For example, F_TO_PT converts a frequency value of Hz in the corresponding period.)

The OSCAT BASIC library build into a CODESYS package can be downloaded from the CODESYS store (https://store.codesys.com/oscat-basic.html).

The OSCAT BUILDING library provides building-automation-specific functionalities. The following are especially worth mentioning:

  • Some very simple actuators

  • Some simple aggregates - BOILER, BURNER

  • Computation of physics

  • Blind modules
